x^3y^-4/x^-2y^-2 simplify
Do you know the rule with negative powers?
you change it to the reciprocal?
Yup so draw that out for me
Yep. \[x^{-n} = \frac{1}{x^n}\]
Can you input the problem in a clearer way?
\[\frac{x^3y^{-4}}{x^{-2}y^{-2}} \]
right?
yeah
@marissalovescats approach is a fine one, but you also just go directly to simplifying if you are comfortable subtracting negative numbers (read: you do it without making mistakes)
"but you can also"
would I subtract the exponets first or do the reciprocal?
Yeah thats what I was thinking ^^^ Because the division bar acts as subtraction for the powers.
let's do it both ways, so you can see which you prefer. do it by reciprocals first...

im not sure if that's right
|dw:1373162447251:dw| I think thats thye recipricol way but I could be wrong @whpalmer4
